Why am I experiencing such short-range and audio cut-offs?

This might happen if the adapter is connected to the back of a desktop computer, where there is a lot of random radio noise generated by the processor and system parts. Moving the adapter to the front of the computer often helps, or use a USB 2.0 extension cable to move the adapter away from the source of the noise. An Intel white paper also confirmed that poorly shielded USB 3.0 ports will cause radio interference. If your device is having range issues when plugged into a USB 3.0 port, a USB extension cable can help.

Why can’t I pair this dongle with my Bluetooth headphones/speakers?

• Make sure your audio devices are Bluetooth as the DG40S doesn’t support 2.4G wireless devices.
• Make sure your Bluetooth headphones/speakers are in pairing mode. Note that powering them on doesn’t automatically mean they’re in pairing mode. The pairing mode status is often indicated by a rapidly flashing LED on the device, please refer to your user manual for instructions.

Note
If they’re connected, but there’s no sound, please set the DG40S as the “Default playback device” in your windows audio playback settings.
